EXTENSION CORDS

FUNCTIONAL DESCRIPTION

Grounded tools require a three wire exten- sion cord. Double insulated tools can use either a two or three wire extension cord. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. Refer to the table shown to determine the required minimum wire size.

The smaller the gauge number of the wire, the greater the capacity of the cord. For ex- ample, a 14 gauge cord can carry a higher current than a 16 gauge cord. When using more than one extension cord to make up the total length, be sure each cord contains at least the minimum wire size required. If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum wire size.

Guidelines for Using Extension Cords

•If you are using an extension cord out- doors, be sure it is marked with the suffix “W-A” (“W” in Canada) to indicate that it is acceptable for outdoor use.

•Be sure your extension cord is prop- erly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified person before using it.

•Protect your extension cords from sharp objects, excessive heat and

damp or wet areas.

WARNING

To reduce the risk of injury, always unplug tool before attaching or removing accessories or making adjustments. Use only specifically recommended accessories. Others may be hazardous.

WARNING

Only use accessories with maxi- mum speed rating at least as high as nameplate RPM of tool.

Selecting Blade

Always use sharp blades. Dull blades tend to overload the tool and increase the chance of kickback (see “Preventing Kickback”). A com- bination blade is included with your tool for general use in wood. Select the right blade for your job. Only use blades with diamond arbors, and read the manufacturer’s instruc- tions before use.

Fig. 1

Rip & Crosscut

A multi-purpose blade for ripping, cross cutting and mitering in hard- woods, softwoods, plywood and composition materials.

Framing-Rip

Designed for fast and accurate ripping along the grain in hard-or softwoods where a smooth cross cut is not necessary.

Plywood-Veneer Recommended for cutting ply- wood, composition materials and all types of wood where a slightly smoother finish is needed.

Finish & Trim

Especially designed for cross cutting and mitering in materials where a very smooth cut is neces- sary. Also cuts aluminum.
